Could any tell why this result

[Tim (PassMark)]

The i7-8550U only has a base speed of 1.8 Ghz, while the i5-8259U runs at 2.30 GHz (the i5 has a much higher TDP at 28W vs the i7 at 15W).

So while the i7 has a slightly higher top turbo speed it can't do as much work as the i5 when there is more than one thread running.

See the attachment it is shows I5-8259u has more benchmarks than i7-8550u, why is is like that even they are same generation too
